In even older literature, the ascomycetes, as we presently understand them, were divided between two groups, the Ascomycota and the Deuteromycota. The latter were often referred to as fungi imperfecti, i.e., species of fungi for which no sexual stage was known. It is now known that these “imperfect fungi”, formerly Class Hyphomycetes in the Deuteromycota, are anamorphs (asexual forms) of the ascomycetes [2].
